Ohm Brew Nic Salts 10ml 18mg Black Jacked: Overview

Ohm Brew Nic Salts 10ml 18mg Black Jacked is a nicotine salt e-liquid from Ohm's Ohm Brew range, sold in the standard UK 10ml bottle at a nicotine strength of 18mg/ml (1.8%). It is made for refillable low-power devices: pod kits, pen-style starter kits and other compact systems that use higher-resistance coils. If you already use a pod kit, or you are moving away from single-use vapes and want something you can refill, this is exactly the kind of product the 10ml nic salt format exists for.

Some background explains why this format is so common. Under UK rules, nicotine-containing e-liquid can only be sold in bottles of up to 10ml, and the maximum nicotine strength is 20mg/ml. That cap applies to nic salts, to freebase liquids and to the liquid inside any pre-filled pod. An 18mg/ml bottle therefore sits just under the legal ceiling, which makes it one of the stronger options you can buy in the UK, and it is aimed at people who want a firm, quick nicotine hit rather than a gentle one. Single-use vapes have also been banned from sale in the UK since June 2025, which has pushed a lot of people towards refillable kits and small bottles like this one.

This page covers what we think a buyer should know before ordering: the specifications, what to expect from the flavour, how the liquid behaves in different devices, nicotine strength guidance, how to fill and look after your kit, what to do when something goes wrong, and an honest look at value for money. Where a figure is typical of the nic salt format rather than printed on this exact bottle, we say so. Always check the label on the bottle you receive for the VG/PG ratio, ingredients, batch number and health warnings, because those details are the authority for your particular batch.

One thing worth saying plainly: this is a nicotine product. It is for adults who already smoke or vape and want an alternative to cigarettes. It is not for under-18s, and it is not for anyone who has never used nicotine. UK health bodies describe vaping as far less harmful than smoking, but not risk-free, and nicotine is addictive. If you are choosing between continuing to smoke and switching, a refillable kit with a suitable nic salt is a recognised route, and your local stop smoking service or pharmacist can give free, personalised support alongside it.

Key specifications at a glance

Before getting into flavour and performance, it helps to be clear on the numbers. The list below sets out what you are buying. Where a figure is typical of the nic salt format rather than printed on this specific bottle, we say so, and you should always check the label on the bottle you receive.

• Brand and range: Ohm, Ohm Brew Nic Salts
• Flavour name: Black Jacked
• Liquid volume: 10ml, the largest bottle size allowed for nicotine e-liquid in the UK
• Nicotine type: nicotine salt (nic salt), where nicotine is bound with an organic acid such as benzoic acid to make it smoother to inhale at higher strengths
• Nicotine strength: 18mg/ml (1.8%), below the UK limit of 20mg/ml
• Total nicotine in the bottle: about 180mg (18mg/ml multiplied by 10ml)
• VG/PG ratio: nic salt liquids are most often balanced around 50VG/50PG, but check the printed ratio on your bottle
• Intended hardware: pod kits, refillable pod systems and mouth-to-lung style tanks
• Suggested coil resistance: roughly 0.6 to 1.2 ohm
• Typical power range: about 8W to 25W, always within the coil or pod maker's printed range
• Bottle features: plastic bottle with a narrow nozzle, a child-resistant cap and a tamper-evident seal
• Fills per bottle: roughly five fills of a 2ml pod, or about three fills of a 3ml tank

The figure that surprises new buyers most is the total nicotine content. A 10ml bottle at 18mg/ml holds around 180mg of nicotine. A single 2ml pod fill therefore holds about 36mg. That is not a reason for alarm, because you absorb only a small fraction of the nicotine in a pod across hours of use, but it is a good reason to store bottles properly, keep them out of reach of children and pets, and never decant liquid into unlabelled containers.

The 10ml size is also a legal feature rather than a marketing choice. If you see a nicotine e-liquid sold in a larger bottle in the UK, that is a warning sign. The size limit, the child-resistant cap and the health warning on the label all exist so that buyers can recognise a properly regulated product at a glance.

Flavour profile: what to expect from Black Jacked

The name Black Jacked echoes the old British Black Jack chew, a sweet with a dark aniseed and liquorice-style taste, and the word 'jacked' suggests a louder, more intensified take on it. The exact tasting notes are printed on the bottle and listed by the manufacturer, so treat what follows as guidance on how a dark, aniseed or liquorice-leaning profile tends to behave in an e-liquid, not as a substitute for the label. If the notes on the product listing point to dark fruit or a different sweet profile instead, the practical advice on temperature, airflow and coils below still applies.

Aniseed and liquorice-type flavours tend to behave differently from the fruit and dessert profiles that dominate most vape ranges. They usually deliver a distinctive, slightly cooling sweetness, a bold middle to the inhale and a finish that lingers on the exhale. They are polarising: people who like the taste of aniseed sweets often find them satisfying and easy to vape all day, while people who dislike aniseed will not be won over by any amount of tuning. If you are unsure whether you like the taste, think about whether you enjoy liquorice, fennel or star anise. That is a better predictor than any description.

Nic salts present flavour a little differently from freebase liquids. Because they are usually vaped at lower power with a tighter airflow, the flavour arrives concentrated and close, with less cloud to dilute it. Many people find that flavours taste sweeter and rounder in a nic salt at the same listed profile, and a sharper note such as aniseed can come across as smooth rather than aggressive. A 50/50 VG/PG balance carries flavour more crisply than a very high-VG shortfill, so expect definition rather than a soft, creamy blur.

A few practical points affect how the flavour comes across on your own setup:

• Temperature: warmer vapes bring out sweetness and intensity but can flatten finer notes and wear the coil faster. Cooler vapes keep the layers separate. Start at the low end of your device's range and nudge upwards.
• Airflow: a tighter draw concentrates flavour. If your pod has adjustable airflow, close it down a little before you decide the liquid is weak.
• Fresh coils: a new coil usually tastes its fullest in the first few days. If flavour fades after a week or two, the coil is the first thing to check.
• Previous flavours: strong flavours linger in cotton. If you are coming from a menthol or fruit-ice liquid, use a fresh pod or coil, otherwise you will taste both at once.
• Nicotine: at 18mg/ml the throat hit is part of the experience. It adds a slight dryness and a bit of weight to the flavour, which suits dark, bold profiles.

Our advice is the same as for any new flavour: buy a single bottle, give it a few days across a settled setup and judge it then, rather than on the first pull from a fresh coil.

Performance and puff delivery

Performance with a nic salt is about how efficiently you get nicotine and flavour, not about how big a cloud you can make. At 18mg/ml in a pod kit, the experience is a compact, flavourful draw with a noticeable throat hit and relatively little visible vapour. People who are used to sub-ohm clouds sometimes assume something is wrong the first time they use a nic salt. Nothing is wrong. The format is designed to be discreet, light on battery and fast to satisfy a craving.

The nicotine delivery is the main point. Nic salts are generally absorbed more quickly than freebase nicotine and feel smoother at high strengths, which is why a 18mg or 20mg nic salt can be comfortable to vape where an 18mg freebase would be unpleasantly harsh. Many smokers find this closer to the speed of a cigarette, and that matters when you are trying to stay off cigarettes. In practice you will often take fewer, shorter puffs with a nic salt than you would with a low-strength liquid, because the craving is met sooner.

As a very rough guide, 1ml of liquid in a low-power pod device yields somewhere in the region of 150 to 300 puffs depending on puff length and power. That would put a 10ml bottle at about 1,500 to 3,000 puffs. Treat that as an estimate for planning, not a promise. Longer puffs, higher wattage and a fresh coil all use liquid faster, and shorter, cooler puffs on a mature coil use it more slowly.

What affects delivery in everyday use:

• Coil resistance: higher-resistance coils (0.8 to 1.2 ohm) give a tighter, warmer, more cigarette-like draw and use liquid slowly. Lower-resistance coils give more vapour and burn through liquid and battery faster.
• Power: within the coil's printed range, more power means more heat, more flavour intensity, a bigger throat hit and faster consumption.
• Puff duration: three to four second puffs are plenty. Longer puffs rarely add anything with a nic salt and can scorch the wick.
• Wicking: a 50/50 liquid wicks easily through most pod coils, so you are less likely to meet dry hits than with very thick liquids, provided you keep the pod filled.

If you want a larger, softer cloud, a nic salt is the wrong tool and a lower-strength high-VG liquid in a sub-ohm tank is the better direction. If you want something small, steady and satisfying, this is the format that suits.

Bottle design and build quality

The packaging is a functional piece of kit rather than a showpiece, and that is as it should be. Nicotine e-liquid in the UK has to be sold in a bottle that is child-resistant and tamper-evident, with a list of ingredients, a health warning, the nicotine strength and a batch number on the label. Expect a plastic bottle with a narrow nozzle that fits into the fill port of most pod cartridges, and a cap that needs to be pushed and turned, or squeezed, to open. The sealing ring tells you the bottle has not been opened before you received it.

The narrow nozzle is the part that matters in daily use. Pod fill ports are small, and a nozzle that is too wide leads to spills and flooding. A narrow tip lets you place the drip point exactly where you want it, and a slightly soft plastic body lets you squeeze gently to control the flow. 10ml bottles are also easy to carry in a jacket pocket or a bag, which suits the way most people use pod kits.

A few things are worth knowing about the bottle in practice:

• Child resistance: the cap is built to be awkward for small hands. That also means it can be stiff for some adults. Use the push-and-turn motion described on the cap rather than forcing it.
• Light and heat: keep the bottle out of direct sunlight and away from radiators, car dashboards and windowsills. Heat and light degrade nicotine and flavouring over time and can darken the liquid.
• Storage: upright, cap tightly closed, somewhere cool and out of reach of children and pets.
• Colour changes: nicotine liquids naturally darken with age and exposure to air. A slightly deeper colour than when you opened the bottle is normal, though a noticeable change in taste or smell is a sign it is past its best.
• Shelf life: look at the date marked on the bottle or the box. Liquids tend to keep best sealed and stored cool, and are generally better used within a sensible period of opening.

When the bottle is empty, rinse nothing into a drain and do not reuse it for anything else. Check your local council's rules for small plastic bottles. Many accept empty, fully drained e-liquid bottles in household plastic recycling, while others direct them to a household waste recycling centre. Pods, coils and devices are a different category, covered in the battery section below.

Coil and mesh technology: choosing the right device

The most important decision you make with a nic salt is the device, not the bottle. Nic salts are designed for low-power hardware with higher-resistance coils. Using one in a high-power sub-ohm tank wastes liquid, produces uncomfortably strong nicotine and often tastes harsh, so it is worth getting the pairing right.

In practice, three kinds of device suit this bottle:

• Pod kits with replaceable pods: the most common choice. A small battery body takes a pod containing a coil and a tank of about 2ml. Coil resistance is usually 0.6 to 1.2 ohm. Pods are quick to swap, which makes them convenient for changing flavour.
• Refillable pen-style kits: a slightly larger battery with a refillable tank and replaceable coil heads, usually around 1.0 ohm and designed for mouth-to-lung puffing.
• Pod mods with adjustable wattage: useful if you like to fine-tune the vape, as long as you stay within the coil's printed range, typically 10W to 25W.

On the coil itself, there are two main constructions you will see. Standard round-wire coils wrap resistance wire around a cotton wick and heat the liquid from the inside out. Mesh coils use a thin, flat sheet of perforated metal with cotton behind it, which gives a wider heating surface and tends to give more even flavour and quicker warm-up. Ceramic coils, common in many closed pod systems, use a porous ceramic that can be consistent and long-lived but sometimes gives a slightly more muted flavour. None is universally better. Mesh tends to reward careful priming and moderate power, ceramic tends to be forgiving, and standard cotton coils are widely available and inexpensive.

With a 50/50 nic salt, coil life is usually decent, because thinner liquid gunks coils less than very high-VG liquids. Sweeter flavours still leave residue on the wick, so you should expect a coil to last roughly one to three weeks of daily use. When flavour dulls, the vapour tastes burnt or the throat hit turns harsh and scratchy, change the coil or the pod rather than raising the power, which only speeds up the decline.

A warning for sub-ohm users: a 0.15 to 0.4 ohm coil running at 50W or more will use an 18mg/ml nic salt very fast and deliver far more nicotine per puff than most people want. If that is your hardware, a lower-strength liquid or a freebase shortfill is more sensible than this bottle.

Battery and charging for your device

The e-liquid has no battery of its own, but the device you pair it with does, and battery behaviour shapes how pleasant the whole experience is. Compact pod kits usually have built-in batteries between about 400mAh and 1,000mAh, with larger pen-style kits going beyond that. Because nic salt devices run at low power, they are relatively frugal, and a moderate user can often get through most of a day on a charge.

As a working guide:

• 400 to 600mAh: small, pocketable kits. Expect a day of light to moderate use, and carry the charging cable if you vape heavily.
• 800 to 1,000mAh: the sweet spot for many people. A full day of normal use is realistic at moderate wattage.
• 1,000mAh and above: larger pens and adjustable pod mods. These cope with higher wattage settings and heavier use.

Charging is nearly always done over USB-C these days. A full charge typically takes somewhere between thirty minutes and two hours depending on the battery size and charger. Good habits protect both the battery and your home:

• Use the cable that came with the device, or a reputable replacement, and a standard wall charger or a computer USB port.
• Do not charge on a bed, sofa or other soft surface, and do not leave it charging unattended overnight.
• Do not use a device with a swollen, hot, damaged or leaking battery. Stop using it and take it to a proper recycling point.
• Do not carry a loose device in a pocket with keys or coins, which can short circuit the contacts.

If your battery is draining faster than it used to, the likely culprits are an ageing coil that needs more power to vaporise liquid, a pod that is nearly empty and drawing hard, or simply a battery that has gone through many cycles. Fresh coils are the first thing to try.

When a device reaches the end of its life, recycle it properly. Lithium batteries start fires when they are crushed in household bin lorries. Take used devices, batteries, pods and coils to a household waste recycling centre or a retailer take-back scheme, and never put them in your general rubbish or ordinary recycling.

Nicotine strength guidance: is 18mg right for you?

Choosing a strength is the decision that matters most when you buy a nic salt. Too low and you will keep vaping to chase satisfaction. Too high and you may feel dizzy, nauseous or jittery. 18mg/ml is a strong option, so it is worth working out whether it suits your smoking habit before you buy.

A rough guide used by many UK vape retailers and stop-smoking services looks like this:

• Heavy smokers (around 20 cigarettes a day or more, or smoking within thirty minutes of waking): 18mg to 20mg nic salt is a common starting point.
• Moderate smokers (around 10 to 20 cigarettes a day): 12mg to 18mg is often enough.
• Light smokers (under 10 cigarettes a day) and social smokers: 6mg to 12mg is usually sufficient. 18mg is likely to be too much.
• Existing vapers stepping down: reduce slowly, for example from 18mg to 12mg to 6mg, over weeks or months rather than days.

Remember that 18mg/ml in a nic salt does not feel like 18mg/ml in a freebase. The salt form makes it smoother and the nicotine is absorbed faster, so a nic salt at a given number often feels both gentler on the throat and more satisfying than a freebase of the same number. If you were previously using single-use vapes at 20mg/ml, the 18mg here is a similar level, slightly lower, and will feel familiar.

Signs you may be on too high a strength include lightheadedness, nausea, headaches, a racing heart, a sore or harsh throat and an urge to chain vape. If that sounds familiar, stop, drink some water, and move to a lower strength. Signs of too low a strength include persistent cravings, frequently topping up, and slipping back to cigarettes. The right strength is the one that stops you wanting a cigarette without making you feel unwell.

The UK limit of 20mg/ml is the maximum you can legally buy in standard e-liquid, so there is no higher tier to go to. If 18mg does not give enough satisfaction, it is usually better to look at the device, airflow and puff technique than to chase more nicotine. Switching to a nic salt from a freebase liquid also tends to need a lower number than people expect, so heavy smokers moving over do not always need the maximum.

If you are pregnant, have a heart condition, high blood pressure or take medication that could interact with nicotine, speak to your GP or pharmacist before use.

Who Black Jacked is for, and who should skip it

Every product suits some people and not others. Being direct about that saves you money and annoyance, so here is a practical breakdown.

Likely to suit:

• Adult smokers, particularly heavier smokers, who want a strong, quickly satisfying alternative to cigarettes.
• Pod kit owners who want a refillable bottle in place of expensive proprietary pods, and who want to choose flavour themselves.
• People moving away from single-use vapes after the 2025 ban who want a simple route into refillable vaping.
• Vapers who like a dark, aniseed or liquorice-leaning flavour, or who want a break from sweet fruit and ice profiles.
• People who value a discreet, low-vapour vape with a tight, mouth-to-lung style draw.

Likely not to suit:

• Anyone under 18, and anyone who has never used nicotine.
• Light smokers, who will probably find 18mg/ml too strong and should look at 6mg to 12mg.
• Cloud chasers with sub-ohm tanks, who need high-VG liquid and low strength.
• Anyone who dislikes aniseed or liquorice, if that is indeed the profile you find on the label. In that case this will not grow on you with tuning.
• People with sensitive airways or a very sensitive throat, who may find a high-strength liquid uncomfortable.
• Anyone expecting a ready-to-use device. This is a bottle of liquid and needs a compatible refillable kit.

An honest note on first-time vapers: if you are coming straight from cigarettes and smoke a pack a day, this strength is a reasonable starting point, and you can step down later. If you are coming from occasional smoking or from no nicotine, it is a poor starting point and a much lower strength would be more sensible.

Finally, if you are buying for someone else, remember that it is illegal to sell nicotine vaping products to under-18s and illegal for an adult to buy them on behalf of someone under 18.

How to use: filling, priming and first vapes

Getting the first few minutes right makes a big difference to how long a coil lasts and how good the flavour is. These steps apply to most refillable pod kits, but always read the instructions that came with your device, because fill ports and safe fill levels differ.

• Step 1, prepare: wash and dry your hands, switch the device off and remove the pod or open the tank according to the instructions.
• Step 2, open the bottle: use the child-resistant cap as intended, and keep the cap and bottle upright when not in use.
• Step 3, fill carefully: place the nozzle in the fill port and fill slowly, stopping just below the maximum line or the point where the fill hole begins. Overfilling is the number one cause of leaks and flooding.
• Step 4, wait before you vape: after filling a new pod or coil, wait five to ten minutes so the cotton fully saturates. Vaping a dry coil burns the wick and ruins the flavour permanently.
• Step 5, take a few primer draws: without firing, draw gently on the mouthpiece a few times to pull liquid into the coil.
• Step 6, start gently: take short, smooth puffs of about two to three seconds at the lower end of the power range, and move up only if you need to.
• Step 7, keep topping up: refill when the liquid level drops to about a third of the tank rather than letting it run dry.

A few extra tips for nic salt users:

• Take slower, shorter puffs than you would with a freebase. The nicotine arrives fast.
• Do not chain vape. Take a few puffs, wait, and see how you feel before taking more.
• Wipe any spilt liquid off your hands and device straight away, because nicotine can be absorbed through the skin.
• Do not mix this liquid with other flavours or add nicotine shots. Nic salts and freebase nicotine are different chemistries, and adding more nicotine to an 18mg liquid would take it above the UK limit.
• Keep your device clean. Wipe the mouthpiece and the battery contacts with a dry cloth now and then.

When you switch to this flavour from another, change the pod or coil if you can. It costs a little more but avoids a muddled taste.

Troubleshooting common problems

Most problems with nic salts come down to the coil, the fill level or the power setting. Here is how to work through the usual issues.

• Burnt or scorched taste: usually a dry or old coil. Check the liquid level, wait longer after filling, shorten your puffs, and replace the coil if it persists. Do not keep vaping on a burnt coil, because the taste will not clear.
• Weak or muted flavour: the coil may be worn, or you may have switched flavours without clearing the old one. Try a fresh coil, tighten the airflow and check you are not running too cool.
• Leaking from the pod or tank: commonly overfilling, a damaged seal or a pod that has not been seated properly. Refill to a lower level, check that the pod clicks in and that seals are intact, and wipe up any spills before use.
• Gurgling or spitting: too much liquid pooling in the airway. Blow gently back through the mouthpiece (with the device off) to clear it, and avoid overfilling.
• Dry hits: the liquid is not reaching the coil quickly enough. Prime properly, keep the tank above a third full and lower the power slightly.
• Throat hit feels too harsh: try a lower power, a looser airflow or a lower nicotine strength. Remember that 18mg/ml is a strong level, so a drop to 12mg may suit you better.
• Dizziness, nausea or feeling jittery: stop vaping, drink water, get some fresh air and wait. If it happens regularly, choose a lower strength.
• Device will not fire or flashes: check the battery, clean the contacts between pod and battery, and make sure the pod is correctly seated. If the device still does not work, try another pod before replacing the battery unit.
• Vaper's tongue: a temporary loss of taste for a flavour you have vaped heavily. Drink water, switch flavour for a day or two and avoid very sweet liquids until it passes.
• Liquid has changed colour or smell: a slight darkening is normal. A sharp chemical smell, separation or an obviously off taste means it should be discarded.

If you have tried these steps and still have trouble, double-check that your coil resistance and wattage match what the device maker recommends. Unmatched hardware causes more complaints than the liquid does.

If liquid gets on your skin, wash with soap and water. If it gets in your eyes or is swallowed, or if a child or pet has come into contact with it, seek medical advice immediately and keep the bottle and its label to show the professionals.

Value for money and how it compares

Value is about the cost per day of vaping and about whether you enjoy the flavour enough to keep using it. The price of a 10ml nic salt is normally in the low single-digit pounds, and the current figure is shown at the top of this page. For illustration, if a bottle cost £4 and you used 2ml a day, you would spend around 80p a day, or £5.60 a week. A 20-pack of cigarettes in the UK now costs well over £14, so a regular smoker who switches can save a significant amount, though the exact saving depends on your habit and hardware.

In honest terms, here is how this format compares with the alternatives you may be considering:

• Versus single-use vapes: disposables are no longer sold legally in the UK, so the real comparison is with the kits that replaced them. A refillable pod kit plus a 10ml bottle costs more up front but is much cheaper per day and creates far less waste.
• Versus pre-filled pods: proprietary pods are convenient but you are tied to one brand and flavour range, and they usually cost more per ml than a bottle. A bottle gives you more choice and a lower running cost, at the price of a few minutes of filling.
• Versus other 10ml nic salt ranges: there are plenty of comparable ranges at similar prices. Differences come down to flavour quality, how consistent each batch is and whether the profile suits you. Some premium ranges charge more for more complex flavours, and some budget ranges charge less for simpler ones. The honest test is to buy one bottle and see if you like it.
• Versus 50ml shortfills with a nicotine shot: shortfills give more liquid per pound but need a sub-ohm device and a different vaping style. If you use a pod kit, a 10ml nic salt is the sensible fit. If you use a sub-ohm tank, a shortfill is better value.
• Versus nicotine replacement therapy: patches, gum and inhalators have a place and are available free or at reduced cost through some NHS stop smoking services. Vaping can suit people who miss the hand-to-mouth habit. It is a personal choice, and you can combine support routes.

Where this product is less good value: if you dislike the flavour after a few days, no price is cheap. If you only vape occasionally, a 10ml bottle may sit around for months, so a smaller or lower-strength option makes more sense. And if you use a very high-powered device, you will burn through bottles too fast to be economical.

Check the multi-buy offers on our site if you vape daily, because buying several bottles at once often lowers the cost per ml. Keep an eye on the date on the bottle and buy in quantities you will use within a sensible period.
